16. Natural specific T cell immunity in patients with B-cell chronic lymphocytic leukaemia (B-CLL) : (A clinical and immunological study)
Sammanfattning : Analysis of TCRBV (T-cell receptor B variable) gene usage of the T cell repertoire in patients with B cell chronic lymphocytic leukaemia (B-CLL) and age-matched healthy control donors showed that major perturbations were more frequently seen in the CD4+ T cell subset than in CD8 population. Analysis of the CDR3 length polymorphism revealed a significantly higher degree of clonality within the CD4+ and CD8+ T cell repertoire of patients as compared to the normal control population.

17. T cells in patients with B-cell chronic lymphocytic leukemia (B-CLL) and multiple myeloma (MM) : an immunological study
Sammanfattning : There are several lines of evidence that T cells in patients with Multiple Myeloma (MM) and B-cell Chronic Lymphocytic Leukemia (B-CLL) are phenotypically aberrant. The overall aim of this thesis was to study T cells with a focus on TCR-signaling pathways in these two B-cell malignancies. The role of T-cells in B-CLL etiology was also examined. LÄS MER
18. Molecular characterization of apoptosis in B-cell chronic lymphocytic leukemia
Sammanfattning : B-cell chronic lymphocytic leukemia (B-CLL), characterized by an accumulation of monclonal B cells, is the most common adult leukemia in the Western world. Defective apoptosis is considered to contribute to cell accumulation, disease progression and resistance to therapy in BCLL. LÄS MER
19. p53 guardian of the genome and target for improved treatment of leukemia
Sammanfattning : P53 acts in several cellular processes as cell cycle checkpoints, DNA repair senescence and the surveillance of genomic integrity. Wt p53 inhibits cancer processes by causing cell cycle arrest and apoptosis. P53 is strongly regulated by the HDM-2 protein, which builds a complex with p53 leading to proteosomal degradation of p53.

20. Genetic changes in lymphoid leukemia
Sammanfattning : It is today generally accepted that the vast majority of malignant tumors arise as a result of genetic changes in critical genes involved in the tightly regulated control of cell growth and cell death. Despite the remarkable progress in the identification of such genes during the past two decades, many cancer genes probably remain to be identified. LÄS MER
